N2 - Comparative calculations with a mathematical model designed by the authors, which takes into consideration
energy transfer from gas flowing through a given channel to gas which penetrates this
channel from an adjacent channel, as well as a model which omits this phenomenon, respectively,
were made for the process of separating gas mixtures carried out with an inert sweep gas in the fourend
capillary membrane module. Calculations were made for the process of biogas separation using
a PMSP polymer membrane, relative to helium as the sweep gas. It was demonstrated that omitting
the energy transfer in the mathematical model might lead to obtaining results which indicate that the
capacity of the process expressed by the value of feed flux subjected to separation is by several percent
higher than in reality.
